Pascal/V Compiler Stack Overflow
The compatibility-mode HP Pascal compiler may stack overflow when compiling large source files, especially when it has been “Qedified” to read files in Qedit format. This is because when we “hook” the compiler to read Qedit files, we steal a couple of hundred words of global storage space from the compiler’s stack. We recommend that you use the $bigcompile$ compiler directive to prevent this stack overflow problem. For smaller source files, this option will slow down the compilation speed.
